目的探讨经尿道等离子体双极电切术(PKRBt)治疗浅表膀胱肿瘤的安全性与有效性。方法用美国AMCI公司的经尿道等离子体双极电切系统行浅表膀胱肿瘤切除术29例。患者男22例,女7例,年龄33～72岁,平均54.6岁。多发肿瘤7例,单发肿瘤22例,膀胱侧壁有肿瘤分布者20例。结果经尿道膀胱肿瘤等离子体双极电切术手术时间15min～65min,无经尿道电切综合征;20例侧壁肿瘤切除时,5例发生闭孔神经反射,但无膀胱穿孔,所有患者术后随访1～33个月,6例复发,均再行经尿道等离子体双极电切术。结论经尿道等离子体双极电切术是一种安全、有效的手术方式。闭孔神经反射是PKRBt常见并发症之一。
Objective To investigate the safety and efficacy of transurethral plasma-bipolar grafting (PKRBt) in the treatment of superficial bladder tumors. Methods A total of 29 cases of superficial bladder tumor resection were performed with transurethral plasma bipolar laser cutting system of American AMCI Company. There were 22 males and 7 females, aged from 33 to 72 years, with an average age of 54.6 years. Multiple tumors in 7 cases, single tumor in 22 cases, bladder tumor sidewall distribution in 20 cases. Results Transurethral resection of bladder tumor with plasma bipolar grafting was performed within 15min ~ 65min without transurethral resection syndrome. In 20 patients with resected side wall tumors, obturator nerve reflex was observed in 5 cases, but no bladder perforation was found. All patients underwent surgery Follow-up 1 to 33 months, 6 cases of recurrence, were transurethral plasma bipolar resection. Conclusions Transurethral plasma bipolar grafting is a safe and effective surgical approach. Obturator nerve reflex is one of the common complications of PKRBt.
